Galois cohomology of abelian groups

Dalton Tarwater

Vol. 24 (1968), No. 1, 177–179
Abstract

Normal and separable algebraic extensions of abelian groups have been defined in a manner similar to that of the field theory. In this paper it is shown that if N is a normal algebraic extension of the torsion group K = Kp, where the p-components Kp of K are cyclic or divisible, and if G is the group of K-automorphisms of N, then there is a family {GE}EX of subgroups of G such that {G,{GE}EX,N} is a field formation.
